1 Volt QRP Transceiver

Members of the DL QRP group are involved in a project to build a QRP transceiver that runs on just 1 volt.

The goals of the project are:

- Save the resources of our earth, save the earth
- Reduce battery waste
- Reduce required materials
- As much fun as possible, so make a real useful transceiver

Details of the project have now been made available on the web. The article says:

"Modern solid state technologies makes it possible to design RF transmitters and receivers with a powers supply as low as 1 Volt with good efficiency. The mainly power consumpting parts, the AF end-amplifier and the RF-PA have to be designed very carefully to give good results and to meet the goals. The efficiency today would be optimal at 3 Volt. This experimental design will be the base for a 3 Volt Transceiver with an RF power of > 0.5 Watt."
